Which didn't tell much, so here is the full log: https://gist.github.com/wormzjl/99a766bb6a92279e0e18a6b9dfd215e9

I don't have both mod through

Too many crash logs opens at once >.<

Going to need to try a binary test method to see when it doesn't trigger.

NEI is just exposing it, it seems. Someting else in there is triggering it fro another mod involved, as NEI and AS alone doesn't cause it. Check the ticket ligands linked above for ther possible mods involved so far that have been found to need to address.

Collapsing this to new master ticket for tracking the incompatibilities until resolved: #762

Please check the listed mods there and confirm if still present after testing with that information.

Confirmed to be an ic2 issue

After disabling NEI it no longer crashes
